Since the 1990s, scientific research has been carried out on the effects of sonar on marine life. This scientific research is reported in peer reviewed journals and at international conferences such as The Effects of Sound on Marine Mammals [47] and The Effects of Noise on Aquatic Life. [48]
While marine pollution can be obvious, as with the marine debris shown above, it is often the pollutants that cannot be seen that cause most harm.. Marine pollution occurs when substances used or spread by humans, such as industrial, agricultural and residential waste, particles, noise, excess carbon dioxide or invasive organisms enter the ocean and cause harmful effects there.
Human activities affect marine life and marine habitats through overfishing, habitat loss, the introduction of invasive species, ocean pollution, ocean acidification and ocean warming. These impact marine ecosystems and food webs and may result in consequences as yet unrecognised for the biodiversity and continuation of marine life forms. [3]
Acoustic noise levels were checked near the course of the America’s Cup in the Hauraki Gulf, New Zealand, in 2021. Sailing events could harm marine life due to underwater noise, study finds Skip ...
Underwater noise pollution due to human activities is also prevalent in the sea, and given that sound travels faster through water than through air, is a major source of disruption of marine ecosystems and does significant harm to sea life, including marine mammals, fish and invertebrates.
The consequences can be enormous to marine ecosystems, including the St. Johns River. Seawater temperatures have hit 100 degrees with all this heat. The consequences can be enormous to marine ...
The noise produced by ships can travel long distances, and marine species who may rely on sound for their orientation, communication, and feeding, can be harmed by this sound pollution. [11] [12] The Convention on the Conservation of Migratory Species has identified ocean noise as a potential threat to marine life. [13]
Noise from human activity in the ocean environment is likely to increase - and become a bigger environmental issue. Discussion of how to minimize the negative effects of noise upon whales, dolphins and other marine-life will no doubt continue between industry, government agencies, military, environmental organizations and academics.
